Effect of the particle size and the liquid content on the shear behaviour of wet granular material

The size of particle is a relevant parameter in the study of the granular material behaviour. For wet granular materials, it affects the capillary force and the number of liquid bridges. We present quantitative and qualitative investigations of the effect of the particle size on the steady-state shear behaviour of partially wet granular material. Two sizes of glass beads have been used: 12–40 μm and 70–110 μm in diameter and the shear behaviour...
